SYSTEM OF,SNOW `DISPOSAL.

SPECIFICATION forming part of Letters Patent-No. 752,911, dated February 23, 1904. Application liled June 30, 1903, Serial No. 163,672. (No model.)

To all whom it may concern,.-

Be it known that I, JAMES C. MARRIOTT, a citizen of the United States, residing inthe city of New York, county of Richmond, and

` State of New York,have invented a certain new and useful System of Snow Disposal; and I do hereby declare the following to be a full, clear,

and exact description of the same, such as will enable others skilled in the art to which it appertains to make and4 use the same.

My invention relates to a system of snow disposal intended particularly for use in removing snow from the streets of cities, bridges,

viaducts, and open spaces generally; and my4 invention consists 1n snow-removal conduits having openings through which snow may be introduced therein, said conduits connected to the water-mains or other suitable sources of water-supply and provided with means for admitting andregulating the flow of water from such mains into the conduits to melt and carry away the snow. These conduits are conveniently located at the curb-lines of streets or driveways and may form the curbs. When sewers'are available, the conduits are preferably connected to the sewers at intervals, so.

as to discharge therein. The openings for the admission of snow with which the said conduits are provided may be continuous, or substantially so, throughout' Athe length of each conduit and arranged to permit snow to be shoveled directly into the conduits, and such openings may be closed by guard-plates which may be removed or moved out of the way when snow is to be passed into the conduits, but which at other times prevent the entrance of articles into said conduits. However, these guard-plates are usully so arranged avoid the necessity of carrying the snow away in wagons, as is Inow the common practice.

A further object of my invention is to remove surface water, such as rain-water, from streets 1n an improved manner and to avoid running streams through exposed gutters: of

streets during heavy rainfalls.

kIn the accompanying drawingsI illustrate one method ofcarrying out myinvention.

In thev said drawings, Figure l is a plan view showing four city streets and in` dotted lines sewers and water-pipes therein, together` -with the conduits for removing snow employed according to my invention. Fig. 2 shows a cross-section of a street, showing the snow-removal conduits, the connections thereof to sewers, and the connection of water-pipes yto the conduits. Fig. 3 is a longitudinal view duits are connected at suitable intervals by'V means of vpipes 4 to sewers 5 or other suitable means for carrying away surface water. and melted snow.

As shown, the snow-conduits 3 are prefer I ably provided with openings adjacent to theV 4 roadway adapted to be closed by guard-plates 6. These guard-plates are capable of being removed or moved out of the way to permit snow to be shoveled into the conduits, and for such purpose said guard-plates may have lips 7 tting within corresponding grooves in the conduits, and thereby supporting said guardplates. These cover-plates do not extend quite.

to the street-surface, openings 8 being left to permit the escape of surface water into the conduits. Such openings, however, are so narrow as to prevent all but the very smallest objects from falling into the conduits, and so becoming lost. Pipes 9 are provided for admitting water from any suitable water-main 10 to the conduits 3, the iiow of water through said pipes being controlled, preferably, by

IOO

suitable hydrants 11, which may also serve as hre-plugs.

In the sides of the conduits 3 ducts 12 may be provided for electric wires or for gas or water pipes. ,Y Y

In the use of this snow-removaly system after a fall of snow the guard-plates 6, which are in sections of such length as to permit easy handling, are removed, and the snow on the surface of the street isshoveled into the conduits 3, water under considerable pressure being admitted to the said conduits at the same time through the pipes 9. Subsurface water, and

particularly that in street mains, always hasl heavily upon the source of supply, stand-pipes or storage-tanks may be located at intervals,

each such tank containing sufficient water for.l

the removal of snow from the territory served by the pipes connected to such tank. Since the snow removal will proceed block by block, water will be turned on only to those conduits which are being used at the time for the removal of snow, and as soon as the snow hasbeen removed from any block or street-section the iiow of water from the street-mains, through such conduit will be stopped, therebyI avoiding drawing too heavily upon the source` of supply. When sewers are not available. to receive the flow from the conduits, the discharge from said conduits may be carried off' in any other convenient manner. i It is obvious that the construction of the con-` duits 3 and their guard-plates 6 may be variedconsiderably without departing from my invention, that these conduits are not necessarily located at the curb-line of a street, and that one conduit may be suficient for each street. It is also obvious that the conduits may be connected to the sewers at such intervals as may be practicable or convenient. I do not limit myself, therefore, to the particularv arrangement and construction of the parts as shown.

In the following claims the term street I is intended to include bridges, viaducts, drivecertainty that rain would be falling at the time when the snow should be removed', and, in fact, rain does not fall ordinarily immediately after a snowfall. Some constantly-available source of water-supply is required-such, for example, as a storage-tank of proper capacity or a street water-main or a pump-and it is such sources of water-supply that are meant loy the term constantly-available source of water-supply7 in the first of the following claims.

What I claim is- 1. In a system for snow removal, the combination of a conduit having openings through which snow may be introduced, a constantlyavailable source of water-supply, means connecting the same with said conduit for admitting water directly thereto, and means for controlling the fiow of water into said conduit.

2. In a system for snow removal, the combination with a conduit extending along a street, and having at a plurality of points openings through which snow may be introduced,

of a sewer or channel connected at intervals to said conduit for carrying away water and slush, a source of water-supply independent of said sewer or channel, and means connecting the same with said conduit for introducing water directly into said conduit.

3. In a system for snow removal, the cornbination with a conduit extending along a street, and having at a plurality of points openings through which snow may be introduced,

and sectional guard-plates normally closing said openings, of a sewer or channel connected at intervals to said conduit for carrying away water and slush, a source of water-supply independent of said sewer or channel, and means connecting the same with said conduit for introducing water directly into said conduit.

4:. In a system for snow removal, the combination with a conduit located at the curbline of a street and forming a curb thereof, said conduit having openings through which snow may be introduced, of means for introducing water into said conduit.

5. In a system for snow removal, the combination with a conduit located at the curbline of a street and forming a curb thereof, said conduit having openingsthrough which snow may be introduced, of a sewer or channel connected to said conduit for carrying away water and slush, and means for introducing water into said conduit.

6. In a system for snow removal, the combinationwith a conduit located at the curbline of a street and forming a curb thereof, said conduit having openings through which snow may be introduced, and guard-plates normally closing said openings, of a sewer or channel connected to said conduit for carrying away water and slush, and means for introducing water into said conduit.

7 In a system for snow removal, the combination with a conduit located at the curb- IOO IIO

line of a street and forming a curb thereof, said conduit having openings in its face adjacent to the driveway of the street, through which snow may he introduced, of a sewer or channel connected to said conduit for carrying away water and slush, and means for introducing water into said conduit.

8. In a system for snow removal, the combination with a conduit located at the curleline of a street and forming a curb thereof, said conduit having openings in its face adjacent to the driveway o the street, through which snow may he introduced, and guardplates, normally closing said openings, sewer or channel connected to said conduit for carrying away water and slush, and means for introducing water into said conduit.

9. In a system for snow removal, the comhination with a conduit located at the curbline of a street and forming a curb thereof, said conduit having openings in its face adjacent to the driveway of the street, through which snow may he introduced, and guardplates, normally closing said openings, open ings being provided, between said guard-plates and the street-surface, for the passage of surface water into said conduit,r of a sewer or of a channel connected to said conduit for carrying away water and slush, and means for introducing water into said conduit.

10. In a system for snow removal, the combination with a snow-removal conduit having at a plurality of points openings through which snow may be introduced, and sectionalguard-plates normally closing said openings, but adapted to be removed, of a water-supply system connected directly to such conduit, for introducing water therein to melt and carry away the snow. y A,

l1. In a system for Snow removal, the comhination with a snow-removal conduit having at a plurality of points openings through which snow may he introduced, of a sewer or channel connected to said conduit for carrying away water and slush, and a watersupply system connected directly to said conduit for introducing water to melt and carry away the snow.

In testimony whereof I aiix my signature in the presence of two witnesses.
